摘要： A handcart may include a frame; a drive wheel rotatably supported by the frame about a rotation axis extending in a right-left direction; a prime mover configured to rotate the drive wheel; a bracket pivotably supported by the frame about a pivot axis extending in an up-down direction; and a non-drive wheel supported by the bracket about a rotation axis extending in a direction perpendicular to the up-down direction. The non-drive wheel may include a first non-drive wheel and a second non-drive wheel, and the first non-drive wheel and the second non-drive wheel may be configured to be rotatable independent of each other.

摘要： A handcart may include a chassis unit and a container unit configured to be detachably attached to the chassis unit. The chassis unit may include a front wheel unit rotatably supporting a front wheel; a rear wheel unit rotatably supporting a rear wheel; a chassis frame extending in a front-rear direction and supporting the front and rear wheel units; and a prime mover configured to rotate at least one of the front wheel and the rear wheel as a drive wheel. The container unit may be selected from a group including at least a first container unit and a second container unit. The first container unit may include a first container and a first container frame extending in the front-rear direction and supporting the first container. The second container unit may include a second container and a second container frame extending in the front-rear direction and supporting the second container.
